Chapter 1661 JNB-17C Advanced Training Fighter

Previous page        Return to Catalog        Next page

    It¡¯s no wonder that Hamilton and Faisal were so gaffe-like. The main reason was that the moment the two planes behind Zhuang Jianye, which were blocked by the curtain, were lifted, it really frightened them.

    Yes, not shocked or shocked, but frightened.

    Needless to say, the fighter jet on the left with jnb-17c painted on the fuselage is the latest improved version of the J-7max. Both the fuselage structure and the overall layout are not only better than the old J-7 series,  The shadow that has no connection at all is its benchmark JJ-7max, which is also very different in appearance compared to it.

    Among them, the biggest change is undoubtedly the most classic double delta wing layout of the J-7max. This is the wing layout inherited from the Yonghong Factory carrier-based fighter project. It was later confirmed by the J-7e fighter and was finally used in the J-7  Teach-on 7max.

    This makes the J-7max¡¯s turning radius and climb rate reach or approach the level of third-generation fighter jets at medium and low altitudes and at subsonic speeds.

    At the same time, the range and bomb load have also been improved, especially the setting of flaps, which has greatly improved the maneuverability of the entire aircraft. It can be said that based on the old J-7 series, this pair of double triangles  The wing has improved its performance several times.

    However, it can be said that the success of the JJ-7max was the pair of double delta wings, and the failure was also the pair of double delta wings.

    Performance and control have been improved, but in terms of supersonic speed, the overall performance has dropped not a little bit. You must know that the top speed of the J-7 can reach Mach 2.2, and even the J-7e has a maximum flight speed of Mach 2.  , but when it comes to the JJ-7max, it only has a mere Mach 1.5.

    This is still in the state of the machine. If it is in the plug-in state and the resistance increases, it will only have a pitiful maximum speed of Mach 0.85. It can be said that the slow speed is pitiful.

    Because of this, although the JJ-7max has attracted great attention from the domestic and foreign aviation circles and received relatively positive praise, it is just like an art film and has not been well-received. The root lies in this place.

    After all, the air force at home and abroad has been generally equipped with third-generation aircraft, which not only have excellent maneuverability at high subsonic speeds, but also perform well at supersonic speeds.

    As an advanced trainer aircraft that is seamlessly connected to third-generation aircraft, it is so slow at supersonic speeds. How do students adapt to the passionate feeling of third-generation aircraft at supersonic speeds?

    So the JJ-7max basic model only sold a few token ones, and was hidden by China Tengfei.

    However, China Tengfei did not terminate the development of the JJ-7max model, but concentrated on continuing to improve it, such as optimizing the air intake, so the JJ-7max-pro and JJ-7max-pro2 appeared.  .

    Another example is the addition of side wings and delta wings, and there are JJ-7max-pro3 and JJ-7max-pro4.

    The next step is to replace the aircraft engine with a larger thrust, so there is a JJ-7max-pro-plus

    In short, after nearly ten years of development, the JJ-7max model has gradually moved from youthfulness to maturity.

    Nowadays, the jnb-17c displayed in front of many princes and nobles in the United Arab Emirates and Saudi Arabia is completely reborn compared to the benchmark JJ-7max.

    The thicker and larger nose fairing can not only accommodate a larger-diameter air search radar, but will also have more space for future upgrades.

    After that, the integrated cockpit canopy is smoother and smoother. The most important thing is the devil's mark-like device integrated on the top of the pilot, which is a leader in the field of cockpit life-saving.

    Because similar facts have only appeared on the F-35 series of fighter jets currently being tested in the United States.

    That is an integrated cockpit rupture and ejection device.

    Unlike the traditional combat aircraft life-saving device that first explodes the canopy and then activates the ejection seat, this integrated pilot life-saving device explodes the cockpit and ejects at almost the same time, and will not be affected by the fragments of the canopy.  And it doesn't hurt the pilot at all.

    In addition to the strict calculation of the direction of the debris flying after the canopy explodes, the most critical thing is that the material of the canopy is made of special light-transmitting composite materials, which not only has high overall strength, but also has anti-ultraviolet, anti-radiation, anti-  Functional efficacy of infrared.

    It can even block the detection of radar waves.

    Of course, the most important thing is that the strength of this material will drop rapidly after fragmentation. Even if the pilot's body is touched, it will not cause fatal injuries.

    Regardless of anything else, this alone is already at the world's advanced level to be precise, it should be the world's leading level.

    The key is that the jnb-17c in front of you is not only an integrated life-saving system. Under its cockpit, there are thick and slender side wings, which are somewhat similar to the f-18, but more like the f-16, but it is said that  It is more suitable to be somewhere between the two.??.

    With the extension of the side wings, there is a pair of wings with a conventional layout.

    Overall, it is much less impactful and complex than the J-7MAX, but those present, especially veterans like Hamilton and Faisal, know that the optimal design of aircraft, especially fighter jets, is in  Subtraction within a complex system.

    Because of this, whether it is a third-generation machine or a fourth-generation machine, the overall aerodynamic layout is becoming more and more concise and smooth. It does not mean that the more advanced it is, the more complicated it will be.

    Because of this, jnb-17c adopts this routine and layout. Not only is it not a failure, in the eyes of experienced people, this is the biggest highlight of jnb-17c.

    In particular, the combination of long and short leading edge flaps on the wing and a pair of ailerons on the trailing edge of the wing not only enable the jnb-17c to have excellent take-off and landing performance, but also have a certain degree of short-distance take-off and landing capabilities.  reduce ability.

    What¡¯s more important is its maneuverability, which must be the best among similar types of aircraft. Especially in dogfights at high subsonic speeds, the jnb-17c can definitely become a nightmare for many second-generation aircraft, and even third-generation aircraft.

    However, what neither Hamilton nor Faisal knows is that for multi-purpose light fighters such as the JNB-17C, which are sold as advanced trainer aircraft, a leading edge wing is enough. The problem is that China is taking off in  The domestic military aircraft field is not dedicated to the development of carrier-based fighter jets.

    The biggest feature of carrier-based fighter jets is that the wings can be folded. Because of this, no matter how complete the leading edge wings or trailing edge ailerons are, they must be divided into two.

    ¡° In this case, China Tengfei will use its mature technology to the extreme, and also open the ailerons and flaps of the jnb-17c.

    ????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? If the navy needs advanced training aircraft to be put on the ship, the jnb-17c can be modified and used.

    Of course, even if Hamilton and Faisal knew the truth about the jnb-17c's flaps opening in two at this time, they would not spare time to think about it, because their eyes at the moment were all focused on the two pairs of side flaps of the jnb-17c.  On the lower air intake, especially the slightly tapered streamlined bulge, my eyes almost popped out of my head, because this was the first time I had seen this pair of clam-type air intakes
